How can I improve mileage on my Vauxhall Insignia?

I just purchased a Vauxhall Insignia and I'm concerned about the fuel efficiency. What are some tips for improving mileage on this car?

One of the best ways to improve mileage on your Vauxhall Insignia is to make sure your tires are properly inflated. Under-inflated tires can greatly decrease fuel efficiency. Regularly checking and adjusting tire pressure can help save you money on gas.

Another tip is to avoid aggressive driving and excessive idling. These can both use up more fuel than necessary. Try to accelerate and decelerate smoothly and turn off your engine if you will be idling for more than a minute.

Proper maintenance is also key for improved mileage. Regularly changing your air filter and getting tune-ups can ensure that your car is running efficiently. Also, keeping up with oil changes can make a big difference.
